Anderson helped Forest Grove open with a bang, nailing a three-pointer on the first possession and adding another two minutes later. She was 3 for 3 from three-point range in the first half, accounting for all nine of her points.

Forest Grove led 10-0 after three minutes, 18-4 after one quarter and 31-10 at halftime.

"I didn't expect (that good of a start) but I'm glad it happened; it was a great way to start league," Anderson said. "We had a game plan, we executed and we came out with a lot of energy -- that was really key."

Jamieson scored eight of her game-high 18 in the fourth quarter and added a highlight-reel block. Senior teammates Madi Andresen and Hannah Swanson added nine and six points, respectively.

Junior Tarea Green had 14 points for the Spartans, who will host McMinnville on Tuesday. The Vikings will host Tualatin the same night.
